Care in using antifreeze
Use a Permanent Antifreeze
(ethylene glycol mixed with corro-
sion inhibitor, antifoam agent, etc.)
meeting the standard requirements
as shown below. With permanent
antifreeze, no change of coolant is
required for a year. If it is doubtful
that an available antifreeze meets
the standard requirements, ask the
supplier
of that antifreeze for
information.

* Never use any antifreeze made
from alcohol which may be a
cause of engine trouble.
* Where no permanent antifreeze
is available, an ethylene glycol an-
tifreeze without corrosion inhibi-
tor may be used only for the cold
season. In this case, coolant
must be changed two times a
year (at the beginning and at the
end of the cold season).
* Do not mix an antifreeze with
one of different brand.
* Absolutely avoid using any water
leak preventing agent irrespective
of whether it is used indepen-
dently or mixed with an
antifreeze.
l Battery
As ambient temperature drops,
battery capacity will drop, and
electrolyte
may
sometimes
freeze if battery charge is low.
Maintain battery at a charge level
of approx. 100% and insulate it
against cold temperature so that
machine can be readily started
the next morning.

* Measure specific gravity of fluid
and obtain rate of charge from
the following conversion table:
>
+ When electrolyte level is low, add
distilled water in the morning
before work instead of after the
day's work. This is to prevent
fluid from freezing at night.
A
To avoid gas explosions, do not
bring fire or sparks near the
battery.

If the electrolyte gets on your
skin or clothes, immediately
wash with plenty of clean
water.
